When you're working on a graphic design project, choosing the right color mode is crucial. It affects how your design will look on screen and in print. Two main color modes dominate the world of design: RGB and CMYK.
Let’s break down the difference between RGB and CMYK, and when to use each.
🔴🟢🔵 What is RGB? (Red, Green, Blue)
RGB is a color mode used for anything digital — screens, websites, mobile apps, and social media posts.
It works by combining different values of Red, Green, and Blue light to produce a wide range of colors. The more light you add, the brighter the color becomes.
Used For:
Tip: Always design in RGB mode if your final output will appear on a screen.
🟡🔵🔴⚫ What is CMYK? (Cyan, Magenta, Yellow, Key/Black)
CMYK is used for print materials. It works by layering inks of four colors: Cyan, Magenta, Yellow, and Black. Unlike RGB, adding more ink makes the color darker.
Used For:
-
Business cards
-
Flyers and brochures
-
Posters
-
Magazines
-
Packaging
Tip: Always convert your design to CMYK before sending it to the printer to ensure color accuracy.
